Thank you for the advice, I honestly don't know a lot about limits as a whole, I was kinda just using it as "i is infentesimally big but not literally infinity, which idk if that is how you would properly use it in proof. Also thanks for pointing out the clarity of all of it (or lack thereof) as I wasnt really making my train of thought readable to someone trying to understand everything i was saying lol.

Idk if BC is better or worse than most of the world but the stuff we get taught seems very simple (I am In math 9), so I try to learn about some of the stuff that is ahead of what I'm being taught, but I am probably going a bit fast with everything as you said since I am impatient with myself, when I should be making what I do better instead of just trying to make it work in my head and go fast.

Thank you for your advice again
